I see most of the links for the 95 games are working, but the majority are links to the original versions of the installers instead of the 2.0 versions (still missing Blade of Darkness and SS2 entirely). I listed them in my thread from yesterday http://www.gog.com/forum/general/missing_20_installers_for_several_games

Mine seem to be working though I didn't try all of them. I'm not too worried about it but my heart goes out the GOG staff that obviously has a long day/night ahead of them. Things like this tend to happen with updates be they minor or major and they'll get fixed. I hope no one gets too upset about it.

Sid Meier's Alpha Centauri has the install working but without the expansion.

I've had that happen a few times too, but it always worked again after re-loading the page. You might want to remove or edit that screenshot, its showing your serial key for the selected game.

Doh! Thanks for catching that, not that I ever play multi-player, but it's my serial, darn it!!

right, honestly, that's not the first time it happends, i mean games links reverted to their old installers.

they really should fixing this definitly, this bug is present from months now :(.

i wonder if it's more obvious right now because they made some changes in the website,...

it's a pain , when you check your collection for updates .The downloader start to download data which isn't necessary in this case & its costs bandwith for both side. For security reasons always make a backup of previous installers before checking for updates.

I have been Downloading the witcher since Tuesday the 6 I have a real shit connection now it's reverted to 1.0.0.10 Geez!

Ouch...the best I can say is to probably have it downloaded to a USB stick somewhere with better connectivity, like a friend's house, a local college, or even a coffee shop (potentially).
